What is it you actually want, the command line passed to MSIExec or the command line used by a Custom Action in the MSI?

For the former, I presume you have an EXE which extracts and executes an MSI. If that's the case, you can normally pass arguments to the EXE to get it to generate a Windows Installer log.

For the latter, you'll be limited to what the MSI itself shows you. Some functions will build their own command lines internally, in which case you'll need to ask the vendor for details.

thanks for attention!

my custom action should no to have knowledge about any bootstrapper.

in log file exists:

REINSTALL=ALL REINSTALLMODE=voums CURRENTDIRECTORY=C:\Documents and Settings\Administrator\Desktop\Server CLIENTUILEVEL=0 CLIENTPROCESSID=1068

and i need string -
REINSTALL=ALL REINSTALLMODE=voums CURRENTDIRECTORY=C:\Documents and Settings\Administrator\Desktop\Server CLIENTUILEVEL=0 CLIENTPROCESSID=1068

Eh?

If there's no bootstrapper, then YOU will have passed the command line!

I suspect what you actually need are the values for the properties REINSTALL and REINSTALLMODE (the others are populated dynamically as the MSI is read).

If so, you can simply use the properties themselves, using the Session object's Property method. An example in VBS would look like this:
